气门活塞极限间隙分析新算法的应用研究

Application Research of New Algorithm for Limit Clearance Analysis between Valve and Piston

基于气门与活塞的运动规律及制造装配误差,构建了一种气门与活塞极限运动间隙的新算法,并利用Excel软件,编制了气门活塞间隙分析程序。以某汽油机为例,进行了计算分析,分析结果显示,零部件的尺寸公差、制造装配误差等对结果影响很大。

Based on the motion law of valve and piston and manufacturing assembly error, a new algorithm for the clearance between valve and piston is constructed. The program of valve piston clearance is compiled by Excel software. Taking a gasoline engine as an example, the calculation analysis is carried out. The analysis results show that the dimensional tolerances of the parts and the manufacturing assembly errors have a great influence on the results.
